It would be interesting to find out why the indian mainstream media falsely claimed that actress Sridevi died of cardiac arrest, when the forensic investigation proves that it was due to drowning, not cardiac arrest
Why did they not wait for the complete investigation to be completed
It is proving to be more interesting mystery compared to any movie
In India, the family may have got away with cardiac arrest, however dubai police are reputed to be very professional in investigating deaths in Dubai,

When Mossad made the mistake of murdering a person in Dubai, the dubai police were able to trace that Mossad was involved, and Israel was exposed, so murdering a person in Dubai is very risky.(source Mossad: The Greatest Missions of the Israeli Secret Service by Michael Bar-Zohar, Nissim Mishal )
